For a limited time, head over to Redbox.com and grab a completely FREE video game rental – no promo code needed. Simply add a video game to your cart and you should see a $3 discount applied at checkout making for a FREE game rental.

This deal appears to be valid online or in the Redbox app AND there appears to be a limit of 2 FREE game rentals per account. If you are wanting to rent more than one game, you do need to do separate transactions as the $3 discount will only be applied once per transaction.
